Jun 28, 2019· A mineral is a naturally occurring crystalline solid that cannot be physically broken down into smaller components.. Deposits of minerals form when a medium that contains and transports mineral-making ore releases and deposits the ore. Magma is one such medium that transports ores. When magma or lava cools, the magma and ore carried within it crystallize to form tiny minerals in the …
